A Python client refers to an application that is written in Python, a popular programming language. Python is popular because of the high level of abstraction available and the extensive library support. A Python client library is a piece of pre-written code also known as a sub-routine or module.

The Python language is considered intuitive to use. It’s easy to read, learn and write with a syntax similar to English. Because it’s simple to use, it improves productivity. It’s also cost-effective since it’s free and open-source.

Python is often used for cross-platform development because it is widely available. Because of its extensive library, it’s beneficial in developing interactive games, web applications, and machine learning systems.
